Large flat back hex

[paphater]

Does anybody have any experience with large flat back hex tanks? I'm thinking of going that direction for my next 10' build but nobody local has one so I'm looking for pros/cons, general experience.

In general they tend to be leak prone. Someone on another forum wanted to set one up and was warned about the failings...... two weeks later it blew. Just be careful and have a back up plan. :)

I'm actually thinking of doing it as a plywood build, so in this case the plywood tank my out perform traditional tanks as all the edges would would be fiber glassed. Still a concern if they are that leak prone.
